I should have specified working radio tuners sorry I apologize for not being more specific. Not sure why it's done exactly but been told it's not the carriers decision but the manufacturers themselves.

LG G5 does have a FM radio chip (Its built into every Snapdragon 820 SoC) but its our carriers that disable it, possibly for the sake of forcing customers to use data (and thus pay more for plans).Recently, T-mobile is US enabled the FM radio chip in the Galaxy S7 but you had to install a 3rd party app (Nextradio) to use it. Its such a shame that carriers disable it because thats one less feature that should have been there and people do listen to FM radio.
